N2 - By the conventional mixed oxide method (1-x)Bi(Mg1/2Ti 1/2)O3-xBaTiO3 ((1-x)BMT-xBT, x = 0.2-1.0) ceramics were prepared. For x ≤ 0.4, a bismuth-rich phase was observed beside the perovskite phase. For 0.5 a;circ x ≤ 0.92 ceramics, all the compositions belong to the pseudocubic phase, while the tetragonal phases were formed when x a;circyen 0.94. With the increase of BT content, a change from a relaxor-like behavior to a normal ferroelectric behavior was observed, while the change of Tbsubesub is in the form of curve. Furthermore, stable dielectric permittivity (1500-3000) and low losses (tan δ < 2%) were obtained in the 0.4 ≤ x ≤ 0.6 ceramics in the temperature range 200°C, indicating a potential for high-temperature applications.
